Question
Jared needs 2.4 micrograms of vitamin B-12 each day. Today, Jared drank a serving of milk containing 0.44 micrograms of B-12 and ate a lamb chop containing 1.224 micrograms of B-12. Which method can Jared use to find the number of micrograms of vitamin B-12 he still needs?
Subtract 1.224 – 0.44 = 1.18, then subtract 2.4 – 1.18.
Subtract 1.224 – 0.44 = 0.784, then subtract 2.4 – 0.784.
Subtract 2.4 – 0.44 = 2.356, then subtract 2.356 – 1.224.
Subtract 2.4 – 0.44 = 1.96, then subtract 1.96 – 1.224.
Subtract 1.224 – 0.44 = 1.18, then subtract 2.4 – 1.18.
Subtract 1.224 – 0.44 = 0.784, then subtract 2.4 – 0.784.
Subtract 2.4 – 0.44 = 2.356, then subtract 2.356 – 1.224.
Subtract 2.4 – 0.44 = 1.96, then subtract 1.96 – 1.224.

To find out how many micrograms of vitamin B-12 Jared still needs, you should first sum the amounts of B-12 he has consumed and then subtract that from his daily requirement.
1. First, add the B-12 amounts from the milk and the lamb chop:
- Milk: 0.44 micrograms
- Lamb chop: 1.224 micrograms
- Total consumed: \(0.44 + 1.224 = 1.664\) micrograms
2. Now, subtract this total from the daily requirement of 2.4 micrograms:
- Remaining needed: \(2.4 - 1.664 = 0.736\) micrograms
Looking at the options you provided:
- The correct method would involve subtracting the total consumed from the requirement. However, none of the provided options reflect the calculations you need to perform directly, as they involve a sequence of subtractions that do not accurately represent the correct overall calculation.
To summarize:
- Jared has consumed a total of 1.664 micrograms of vitamin B-12.
- Therefore, he still needs 0.736 micrograms to meet his daily requirement of 2.4 micrograms.
If you were to relate it back to the options, the correct approach is not listed directly among the options provided.
